To ztZl whom it may concern.-

Be it known that I, J OrrN H. DAVIS, a citi- Zen of the United States, residing at Hamilton, Butler countyfOhio, have invented cerain new and useful Improvements in Tank- Valves, of which the following is a specification.

This invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a side elevation, part vertical section, in the plane of line b of Fig. 2 of my improved tank-valve; Fig. 2, a plan of the structure with the valve-chamber removed, and Fig. 3 a vertical section of parts in the plane of line a of Fig. 2. r

In the drawings, 1 indicates a side wall of the tank; 2, the floor of the tank; 3, the nose of the supply connection projecting below the tank-tloor; 4, the flattopped flange on the upper end of the nose; 5, the gasket between the nose-flange and the tank-floor; '6, nut On the nose under the tank-floor for clamping the nose to place and compressing the gasket 5; 7, ears projecting sidewise from the flange 4; 8, a plate separably disposed upon the flange 4 and having a central aperture through it, this plate forming the valve-seat; 9, the, valve-chamber having an integral roof and having an open base seating downwardly upon the upper surface of plate 8; 10, the valve inthe form of a plug working loosely through the roof of the valve-chamber and engaging downwardly upon the valve-seat"; 11, lever mechanism connected with the valve and valve-chamber and serving as the agency through which the usual float operates tne valve; 12, a gasket disposed between flange 4 and plate 8; 13, screws passing through ears projecting from the base of the valve-chamber nd from the edges of plate 8 and screwing i to the ears of flange 4; 14, notchesin the periphery of plate 8 extending inwardly atrifle beyond the inner wall of the valve-chamber, and 15 outlet-ports formed between the inner wall of the valve-chamber and the inner walls of the notches in the plate 8.

In Fig. 1 the valve is shown as being seated upon the valve-seat, to which it is held by the action of the float and the connecting mechanism. When the float descends, then the valve rises and the supply-water passes upwardly through the aperture in plate 8 and enters the valve-chamber 9 and discharges downwardly through ports 15, the valve reseating and the inflow ceasing when the refilling of the tank should have carried the float to proper height.

By simply removing screws 13 the valvechamber, valve, float, and connecting mechanism may be at once removed as a whole, and then the plate 8 may be removed for repair or renewal, all the parts being again assembled by an obvious operation.

I claim- In a tank-valve, the combination, substanworking axially through the roof of the valvechamber and engaging the aperture of the valve-seat, and float-operated mechanism carried by the valve-chamber and connected with the valve.
